Walmart rolls out light-up digital shelf labels to help shoppers find items

Walmart is deploying a Shop to Light feature that flashes a digital shelf label when a shopper looks up a product in its app. Store associates use the same labels for Pick to Light and Stock to Light. All three tools will reach stores companywide by the holiday season.

• Shop to Light has logged 5 million flashes since summer
• Digital shelf labels are in more than 4,300 stores
• A typical Walmart store carries about 120,000 items
• Prices are updated overnight with human oversight
